4.TEST EQUIPMENT
4.1 Door Provide a door structure of a conventional wood or metal door that is not mortised for hinges, or a skeletonized structure having an equivalent center of gravity in all directions after weights are applied.Hinge mounting surface of a door shall be a continuous steel strip with a minimum thickness of 1/4 in (6.4 mm). The dimension from the hinge axis to the edges of the mounting surfaces and to a plane parallel to the door face through the center of gravity of the door are listed in 8.2 for all sizes of square, full mortise hinges.Test door width is 36 in (914 mm).
4.2 Jamb A rigid, vertical steel jamb that is not mortised for hinges with a minimum thickness of 1/4 in (6.4 mm) shall be erected to hang the test door. Hinge mounting surfaces shall lie in the same plane and be plumb. Door stops or latching devices shall not be used. The door shall swing freely through a 90 degree test arc.
4.3 Blocks Steel jamb mounting blocks 1/4 in (6.4 mm) minimum thickness shall be provided for each of the hinges. They shall be of such rectangular dimensions as shall accommodate the leaves of the specimens and shall be over- sized to the extent that three 1/2 in- 20x 3/4 in (12.7 mm- 20x 19 mm) hexagon head cap screws plus lock washers shall be applied to each block making it tight to the jamb (see 8.2). Holes for these cap screws shall be of such diameter as shall permit 1/8 in (3.2 mm) adjustment in all mounting plane directions before tightening.
4.4 Drilling Hinge jamb mounting blocks as well as door hinge mounting surface shall be drilled and tapped in accordance with the following: Template: Within .005 in (0.13 mm) of true position as shown by manufacturer's template drawing. Non-template: Within .005 in (0.13 mm) of the hole locations of the particular test specimen. Both hole patterns shall be accurately placed so that hinge-pin axes be normally collinear.
5.1 Hinges to Test Tests described apply only to square full mortise hinges. Providing that narrow widths or companion hinges such as half surface, half mortise and full surface types have a similar barrel construction, certification of square full mortise hinges shall apply to these other types. The manufacturer shall attest that barrel constructions of these other types (in any one size) are identical in all significant respects.
5.1.1 Plain bearing non- ferrous hinges, pivot hinges and olive knuckle hinges shall not be tested and have been included in this standard for informational purposes only. The grades given in the type numbers for these hinges are informational guidelines for relative door weights. Please consult manufacturers catalogs for additional details.BHMA A156-1 pdf download.
